Wheal Maid
There are records of Wheal Maid (also known as Wheal Maiden) being worked in the 1770s and by 1780 it had been amalgamated into the Great Consolidated Mines. It is shown on a map from 1819 stretching to a depth of 130 fathoms below the drainage adit and profits from 1800-1840 are said to have reached £200,000 which is equivalent to around £20 million today. The mine was still producing copper and tin in 1865 as part of St Day United Mines but was making a loss by this point. Some exploratory mining was done in the mid-1980s of the interconnecting network of mines in the area which also involved connecting these to Wheal Jane.
